The working principle of automobile blower

The working principle of a car blower mainly depends on the operation of the motor, which drives the blades to rotate, allowing air to be sucked in and blown out. Specifically, when the motor is powered on, its internal magnetic field rotates and interacts with the blades, causing them to rotate. As the blades rotate, air is drawn into the blower and then blown in a specific direction through the guiding effect of the casing.

In addition, the car blower also has some auxiliary components, such as speed control switches and temperature control switches, used to adjust the speed and temperature of the blower. These switches regulate the speed and temperature of the blower by controlling the on/off of the motor power supply or changing the voltage of the power supply.
